摘　　要：在天然河道上修建枢纽,必须保证原河道洪水流量的渲泄。大顶子山航电枢纽在预可、工可和初步设计阶段,利用比尺为1∶130整体定床正态模型,对枢纽总体布置曾进行了多方案的对比试验。文中根据物理模型泄水闸泄流能力方面的试验成果,提出了枢纽泄流方面存在的问题,通过对枢纽泄水闸孔数、泄水闸堰型、堰顶高程等多种有效改善措施,提出了满足枢纽泄流能力的平面布置方案。To build a hydro-junction in a natural river, the flood discharge must be large enough. In the stage of feasibility study and preliminary design of Dadingzishan Hydro-junction Project, comparitive tests on the general layout were performed by the normal fix-bed model with the scale of 1 ： 130. On the basis of the test result of physical model, the problems in the junction discharge capacity are proposed, and plan layout satisfied the discharge capacity of the junction is proposed by various effective improving methods, such as the hole number of the lock, weir type and crest elevation.
